Interesting article, Janine. Thanks for raising the topic. A couple of clarifications... Chiming in as the Chairman of a different standards group, WirelessHD (not WHDI), I'd emphasize that WirelessHD was the first group to launch a wireless, uncompressed HD video standard, preceding WHDI by over a year. And the 1 year has made a huge difference. WirelessHD chose to focus on the 60GHz frequency band because the only way to transmit video over the constrained 5GHz channel was to compress and/or "drop bits" (thereby degrading video quality), which is what WHDI technology does. However, WirelessHD maintains a bit-for-bit accuracy of what was sent versus received, making it truly uncompressed and lossless and superior quality. Further the architecture is such that the cost is comparable and in many cases lower, so products are entering the market at the lowest price points, thus several comments to that effect above. WirelessHD is also the only standard that has products that support 3D. And it is the only standard that will support future 4K resolutions as well. Last, WirelessHD supports data transmission for high-speed transfer of your content (multi-gigabyte movies and such) from device to device, whereas other standards do not. There is certainly tremendous momentum behind WirelessHD, while other solutions continue to struggle. The recent launch of the Alienware M17xr3 from Dell is a great example of this - an embedded PC solution for WirelessHD! Thanks again for your coverage of the topic!

Good point - I did some quick looking up on this. I am not sure about WHDI, but WirelessHD does support 3D. The Rocketfish WirelessHD adapters from Best Buy mentioned above is an example of 3D support.

Wireless for truly uncompressed video is amazing, not sure if this tehcnology scales up to support 3D

Janine, Bowho In this area I have mostly seen products based off the WirelessHD standard in action, which is based on the 60GHz technology and am very impressed with the performance (truly uncompressed 1080p video, given the high bandwidth available in this spectrum). Here is the link to the WiHD standard if you want to learn more: www.wirelesshd.org Products based on this standard have already hit the market, see below: http://www.bestbuy.com/site/Rocketfish%26%23153%3B+-+4-Port+WirelessHD+Kit/1254005.p?id=1218244145025&skuId=1254005 I have also increasingly been hearing about gaming platforms from Dell Alienware which is using the same WirelessHD technology. http://www.geekwithlaptop.com/alienware-m17x-steals-the-show-at-pax-east-2011 This standard looks more promising, with actual products from top CE and PC customers in the market already!

3Gbps in a 40MHz channel?! Have you heard of the Shannon limit of the channel capacity? So, I guess the trick is the so called "equivalent" video data rates ... News like this really amuse me!
